A sample of 0.0400 mol potassium hydroxide, KOH was dissolved in water to yield 20.0 mL of solution. What is the molarity of the solution? 0.4M
250M
2.0M
2.00x 10-3M

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
